Impressive defunct experiences you've been able to enjoy

I’ll add 4 that weren’t mentioned…Honey, I Shrunk the Kids playground @ MGM/Hollywood Studios…my DW & I first experienced it on our “Disneymoon” in 1993 and then took our kids who loved the area…

20k @ MK…again, rode it in ‘93 yes, it wasn’t technically advanced, but it WAS fun!

The hunt for the paint brushes on TSI early in the morning…our girls LOVED the hunt!

IMHO, the best experience I had was for my birthday my wife and kids bought me the Segway around the WS tour…I did it solo with a group of about 10, we learned how to “drive” a Segway and then toured the WS before it opened for the day…
THAT was a tour to experience!!

Honorable mentions: the liquid cheese & the giant sugar cookies at the Writers Stop @ HWD

Getting the full experience included when dining at Cinderella's castle - a personal meet and greet with Cinderella in her own area with backdrop before the meal with a printed photo of the meet provided at the end of the meal, plus the wand or sword and wishing star, and all of the characters individually stopping at your table to chat for a while. Magical and worth the price for all that. Food was awful though and so was the service. lol

The Hunchback of Notre Dame show. I don't like movies. I dislike stories. I sleep during most "shows." This one enthralled me. Its the only show I enjoyed. I couldn't wait to see it again just to find out it was discontinued.
